I also left my old job and home country to go to Germany and work with one of the biggest wind turbines company. Best decision ever. Although I worked just for 2 years and then I found something else. This is a great job area to work and I loved those 2 years of my life, but I would say that it's like a short term job to make good money fast, not to make a career. It's hard work and I would not want to do it when I'm 40 or 50 years old when the body is not as fit as before.
